Blacklist

In information security, blacklist is a list in many spam, spyware and IP filtering systems compiled by the user or administrator (or the vendor) that access is disallowed. For example, an anti-spam blacklist will be a list of IP addresses from which mail will be blocked; a web filtering blacklist is a list of websites that the user cannot access due to its contents or high risk of spyware activities.
